Description

TECHNICAL FIELD [0001] The present invention relates to a distribution board having an air circulation type moisture removal function,

[0001] The present invention relates to an air conditioner having an air circulation type moisture removal function, and more particularly, it relates to an air conditioner which circulates air through a fan (FAN) to remove moisture in the cabinet, thereby preventing a short circuit caused by moisture, condensation, Electric parts and the like are prevented from being damaged by moisture and moisture.

In general, switchgear is an electrical facility that supplies industrial power to users securely, and is a device used for monitoring, controlling, and protecting electrical systems when power is sent from a power plant or substation to a customer several times.

Such a switchboard consists of a structure that attaches and supports unit devices such as a breaker or a protective relay, and a collection of conductors that connect and connect the unit devices, and these various electric devices are safely insulated and housed in a rectangular steel housing .

Such switchboards are configured to convert power to commercial low voltage and supply power to small area units or building units. However, there is a high risk of fire due to heat generation in high voltage parts such as high voltage transformers and switch contacts inside.

In this way, the internal temperature of the enclosure of the switchgear is relatively higher than the external temperature due to the heat released from the device itself, the heat transmitted from the concrete floor, and the geothermal heat radiated from the concrete floor. The condensation is generated in the inside of the apparatus and moisture is generated. In severe cases, condensation forms, and the condensation causes corrosion of the line, resulting in an increase in the maintenance cost and shortage. Also, Since the electric devices are built in, the internal temperature rises.

In particular, when the switchboard is installed outdoors, the enclosure made of steel directly receives solar heat, so the internal temperature rises further and condensation (dew condensation) occurs due to the diurnal variation, It degrades operation efficiency and function.

Further, it is difficult to maintain due to a trouble due to high temperature, a short circuit, etc. Particularly, the parts and electric devices built in due to high temperature deteriorate and shorten the service life.

In view of the above problems, the applicant of the present invention circulates the air inside the switchboard through the fan to maintain the inside of the switchboard at a predetermined temperature, as well as to prevent moisture from being leaked due to moisture and condensation, The present invention has been focused on.

In the present invention, a fan capable of circulating air is installed inside the cabinet main body, and a minute guide temperature change of internal equipment of the cabin is monitored to constitute a separate guide unit for controlling the circulation of air uniformly to each equipment .
